SASH SUPPORT AND LOCK.

sPEcIFIcATIoN forming part of Letters Patent No. 541,810, dated .rune25, 1895. Application iiled October 3,1894. Serial No. 52512767. (Nomodell) To all whom it may concern:

Be itknown that 1, WILLIAM WESLEY Dw1- GANS, of Arkadelphia, in thecounty of Clark and State of Aukansas, have inventeda new and ImprovedSash Support; and Lock, of which the following is a full, clear, andexact description.

My invention relates to an improved device for supporting and lockingwindow sashes, and has for its objects to provide a novel device of thetype indicated, which Willloe exceedingly simple and inexpensive, beadapted for ready location on any Window having vertically movablesashes, and afford convenient means to support the sashes at any pointof sliding adjustment, and lock the same in a completely closedcondition.

To these ends my invention consists in the construction and combinationof parts, as'is hereinafterdescribed and indicated in the claims.

` Reference is to be had to the accompanying drawings, forming a part otthis specification, in which similar figures of reference indicatecorresponding parts in all the views shown.

Figure 1 is a transverse sectional view of a window easement in part,the lower portion of a sash, and the improvement applied and adjusted tosupport the sash in a partly ele vated condition. Fig. 2 is a transversesectional view on the line 2 2 in Fig. 3, showing the lower portieri ofa sash, a easement in part at one corner of the same, and the improvedsash support and lock, adjusted to lock the sash in closed adjustment.Fig. 3 is an inner side view of a lower corner portion of a windowcasement,'the lower part of a sash in closed adjustment, and theimprovement shown partly by dotted lines, and adjusted to lock the sashin a closed condition; and Fig. Il is an enlarged transverse 'ectional`view of the lower part of a window c sement at one corner, a lowerportion of a sash therein in closed condition, and the improved sashsupport modified in construction so as to adapt it for sustaining thesash at any point of sliding adjustment and avoid locking it..

The easement portion l0, may be part of a window having an upper and alower sash, or

be a portion of a car window easement. The

strip 1l, representing the outer bead strip of a oar window sash, or ofan upper sash for a 4window having two sashes, may also indicate theparting strip that separates 'the upper and lower sashes of a windowhaving two vertically sliding sashes.

For the purpose of illustrating the construction and operation of theimproved sash sup` port and lock, thedevice is shown in connection witha single sash window.

The window sash 12, is designed to be vertically slid to operi theeasement and isretained in the latter free to slide, by a pair of thestrips 1l, that have a loose contact with the outer surface of Atheupright side bars of the sash, and also by two inner bead strips 13,that are adapted to loosely impinge the inner side surface ot the sidebars, one ot' said bead strips being shown in the drawings.

The improved sash support and locking device, comprises a series ofspaced pockets 14, that are formed in the bead strip 13, penetrating theside of said strip that has a loose contact with the sash, a singlerecess or pocket l5 in the `side bar ot' the sash, located near thelower end of said bar,a spherical ball 16, that occupies the pocket 15,and may enter either pocket 14, and push pieces 17, which have a looseengagement with the bead strip 13, one opposite each pocket therein.

The pocket 15, that is` formed in the side of the sash side bar, isshaped as shown in cross section in Figs. 1, 2,and 4, it; beingan'excavation of suitable depth and width, proportioned to suitthediameter ofthe ball 16, having its lower wall sloped upwardly in a curvethat terinitiates in a semicircularcavity abovethe ineline mentioned,the semicircnlar portion. ot` the pocket., which is its deepest part,being adapted to loosely receive the ball 16, that when located thereinis completely embedded, and avoids contact with the bead strip when thesash is elevated. The pockets 14, which are formed in the bead strip 13,are provided in sufficient number to suit the dilerent heightsat whichthe sash is to be sustained by the improvement.

As shown, the pockets la, that co-act with the other features of theimprovement t-o support the sash, are of a like form, each consisting ofa cavity that is curved in its defining wall at the lower part of thesame,'and from the curved portion is upward ly and outwardly slopedtoward the inner face of the bead strip, or surface that is penetratedby the pockets.

The relative depth of the lower part ot each pocket `14, is such withregard to the dimension of the ball 16, that the latter when introducedin either of said pockets, will be embedded Overhalt' of its diameter,and thus be adapted to remain seated in the same until it is designedlyremoved.

Referring to the pocket 15, that is produced in the sash 12, it will beseen that a slope 18, is formed on its upper corner, by removing thematerial, this inclined Wall being provided to impinge the ball 16, forthe support of the sash, as will be further explained.

The push pieces 17, are alike and one is provided for each pocket 14,each piece consist-A ing of a rod having a suitable length that willallow it tO be loosely inserted in a perforation formed to receive it inthe bead strip 13, these perforations that penetrate the lower portionsof the pockets, being similarly in clined downwardly, as shown in Figs.1 and 2.

The perforations for the push pieces are each diametrically enlarged attheir inner terminals to receive the heads 19, that are formed l on thepush pieces 17, at their inner ends, push buttons 20, being affixed tothe outer. ends ot' the same, the weight of which causes the push piecesto slide into the positions shown, so as to enter their heads in thecountersunk enlargements Ot the perforations, and project their pushbuttons away from the bead strip when free to do so.

The operation of the sash support is as follows: Assuming that the sashis completely closed as shown in Fig. 4, and that the entire series ofpockets 14, are Ot' a similar formal ion, it will be seen that 'theelevation of the Sash will cause the ball 16, to roll up the inclinedside of thelowermost pocket 14 it has entered from the pocket 15. Thecontinuation of upward movement of the sash, will push the ball into thepocket l5, so that when the lower pocketI 14 has been passed, theballwill be loosely retained free from the bead strip 13, until anotherpocket 14 is reached, when the ball by its gravity will be caused toenter said pocket from the pocket 15.. After a sufiicient number otpockets 14 have been passed by the expulsion of the ball 16 from themsuccessively,to attain a desired height for the sash, it may be retainedin position by its adjustment so as to impinge the sloped wall 1S of thepocket 15, on the ball, that is then seated in one ot the pockets 14, asis shown in Fig. 1, it being evident that such an adjustment of partswill maintain the sash and prevent it from sliding downwardly.

To release the sash that is supported as has been explained, it isnecessary that the sash be elevated, and the push piece 17 thatisopposite the pocket 14 occupied by the ball, be pushed inwardly so as toexpel the ball from said pocket, which will permit the sash to be slidto close the window if there are no intervening pockets 14, and if thereare one or more pockets below the one from which the ball has beendislodged,the push pieces of these pocki ets must be manipulated toprevent an entrance of the ball.

When the improvement is to be used as a sash lock as well as a sashsupport, a pocket 21 of a semi-circular shape is formed in the beadstrip 13, at such a point as will locate its lower edge about level withthe nearest edge of the lower surface of the pocket 15 in the sash, whenthe latter is closed, as shown in Fig. 2. After the pockets 15 and 21are oppositely positioned as has been explained, the ball 1G'will by itsgravity be caused to enter the pocket .21, and as the slight loosenessof the sash will adapt the lower edge of the pocket 15 to bear on theball so as to retain the latter seated in the pocket 21, it an attemptis made to raise the sash, it -will be evident that the latterwill be'locked from elevation until the ball is removed trom the pocket 2l by amanipulation of the push piece that is opposite said pocket.

It is claimed for the improved sash support and lock that it isexceedingly simple andinexpensive, that it can be applied to any windowhaving vertically movable sashes, thatit will reliably` sustain thesashes at different points of elevation, and also automatically lock thewindow in closed adjustment.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A sash support, comprising an inwardly andupwardly curved pocket in the side bar of' the sash near its lower endsaid pocket having a sloped wall at the top edge, a plurality otdownwardly and inwardly curved pocketsin the bead strip that covers thepocket in the sash, push pieces adapted to enter the pockets andprojecting out through the bead strip, and a spherical ball interveningthe sash and bead strip and adapted to enter the pockets therein thepocket of the sash being of a depth greater than the diameter Ot' theball, substantially as described.

2. A sash support and lock, comprising a pocket in the sash at one sidenear its lower edge, the said pocket having a sloped upper edge, aseries of pockets in the bead strip that covers the pocket in the sashsaid pockets being upwardly and outwardly sloped, a semicircular lockingpocket in the bead strip below the series of pockets therein, pushpieces in the pockets in the head strip and projecting out through thesaid bead strip, and a ball adapted to traverse the upper series ofpockets inv the bead strip when the sash is elevated and interlock witho ne of said pockets and the sloped edge of the sash pocket to supportsaid sash, and interlock with the lowermost pocketin the strip and thepocket in the sash to hold the sash completely lowered the pocket of thesash being ot a depth greater than the diameter Of the ball,substantially as described.
